Out of 500 inspected units, 35 require rework. What is the rework percentage?
Correct Answer
D) 7%
Rework percentage is 35 / 500 = 0.07 = 7%.
Why This Is the Correct Answer
Rework percentage is 35 / 500 = 0.07 = 7%.
Why the Other Options Are Wrong
Option A: 5%
rework percentage, choice a: 5% omits a required add-on/subtraction; the numeric gap is 2.
Option B: 12%
rework percentage, choice c: 12% backs into 0.34 when divided by 35; the accepted setup gives 0.2 on that same base.
Option C: 14%
rework percentage, choice d: 14% backs into 0.4 when divided by 35; the accepted setup gives 0.2 on that same base.
Memory Technique
Picture a badge labeled rework percentage: finish every operation before accepting 7%.
